Abstract
A mass flowmeter operating by the Coriolis principle, with one essentially straight fluid-conducting Coriolis measuring tube, at least one oscillator associated with and exciting the Coriolis measuring tube, at least one detector associated with the Coriolis measuring tube and capturing the Coriolis forces and/or the Coriolis oscillations generated by Coriolis forces, and a compensating cylinder in which the Coriolis measuring tube is mounted by way of a mechanical connection to the compensating cylinder. The measuring accuracy of the mass flowmeter is further improved to a considerable extent by balancing both the excitation oscillation and the Coriolis oscillation of the Coriolis measuring tube within the compensating cylinder.
